Question

what is a proof for a triangle?

Answer 1

A triangle that you would use on a pool table that holds the balls

Answer 2

I dont follow

Answer 3

what do you mean

Answer 4

@dhagen do u have 3.06 and 2.06

Answer 5

for geometry

Answer 6

Step 1: Line/ Angle Proof
A. Find vertical angles, two parallel lines with a transversal that intersects them, or a perpendicular bisector in your everyday world. Take a picture of it. Place image below.






B. Create a proof for the image above. You must use one of the following theorems: Vertical Angles, Corresponding Angles, Alternate Interior Angles and/or Equidistance of a Point on a Perpendicular Bisector.











Step 2: Triangle Proof
A. Find a triangle in your everyday world. Take a picture of it. Place image below.






B. Write a proof for the image above. You must use at least one of the following theorems: Triangle Sum, Isosceles Triangle, Converse of the Isosceles Triangle, Midsegment of a Triangle or Concurrency of the Medians of a Triangle
that's 3.06

Answer 13

Let me think about this. I assume you picked a pool table rack

Answer 14

yes

Answer 15

You don't "prove triangles", but you can prove that triangles have certain properties.

For example, all triangles have angles that add up to 180º

Answer 16

okay thank you!

Answer 17

for
***Step 1: Line/ Angle Proof
A. Find vertical angles,
****

vertical angles are formed by an X shape
find something that makes an X shape

Answer 18

hmm railroad sign

Answer 19

ok, that works. The property of "vertical" angles is that they are equal
Here is a proof.

Answer 20

do I just copy that proof to

Answer 21

I would try to understand it, not just copy it.

Answer 22

Okay thank you
